SPECIFICATION forming part of Letters Patent No. 587,395, dated August 3, 1897. Application led September 29, 1896. Serial No. 607,284. (No model.)

.To all whom t may concern..

Be it known that I, JOHN ILLINGWORTH, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Rolling-Machines for Finishing Shafts or Rods of Metal; and I do hereby declare the following to beaf ull, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters and numerals of reference marked thereon, which form a part of this specification.

The object of this invention is to manufacture at a reduced cost a cold-rolled round steel rod or shaft having'a high polish; and it consists in the improved rolling and finishing machine and Vin the arrangements and combinations of parts, all substantially as will be hereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like letters and numerals of reference indicate corresponding parts in each of the views, Figure 1 is a plan of the newly-invented machine. Fig. 2 is a detail front view of a portion of a certain pillow-block. Fig. 3 is an end view of the machine. Fig. 4L is a sectional detail showing in end view certain adj ustable guides and their cooperating parts of Fig. 1. Fig. 5 is a vertical section of Fig. 4 at line y. Fig. Gis a side View of one of the pillow-blocks above referred to. Fig. 7 is a rear view showing portions of the machine, and Fig. 8 is an exaggerated detail view showing the form and arrangement of the rolls in their relation to the shaft or rod being operated upon.

In said drawings, a indicates a bed-plate having suitable bearings for gear-wheels, rolls, and other working parts. .Of said bearings those marked b b are for the shaft or rod-reducing rolls c c, between which rolls the shaft or rod to be acted upon is guided. The said bearings b b are formed and arranged to hold the rolls at slight inclinations to the line` of movement of the rod, as indicated in Fig. 8, so that as the rolls rotate on their axes and engage the periphery of the rod at the opposite sides thereof said rod will not only be turned on its axis, but will be fed longitudinally forward to the grinding and polishing Wheels, at the same time being reduced in diameter under the opposite pressure of the said rolls, so that the grain of the metal is made compact, and the said metal gives the advantages due to cold-rolling. This inclination of the rolls and their axes is but slight, and consequently does not appear in Figs. l and '7 of the drawings, but is indicated in Fig. 8. The inclination of the rolls is sufficient, however, to effect a slow forward longitudinal movement, as above indicated. The shape of the periphery of the rolls is also indicated in Fig. 8, where said rolls to an exaggerated extent are rounded at the edge, as at c', where the rod is lirst brought in contact with them, then convexed, so as to compress and reduce the diameter of the rod, and toward the opposite or farther edge of the rolls are made straight, as at c", and a shade smaller in diameter than the convex portion, so as to just touch the rod and straighten and render said rod smooth before passing from between said rolls.

The means preferably employed for operating said rolls are shown in Fig. l, where upon the bearings d d at one side of the bearings l) b are journaled gear-wheels d d on shafts f f, which gear-wheels engage or intermesh with gear-wheels ee on shafts f f. These latter shafts are provided with gearwheels g g, which mesh with small pinions 7L upon shafts 't' t' with large gear-wheels j j. The large gear-wheels jj are made to rotate together, but in opposite directions, by means of an intermediate gear-wheel k, and are driven by a small pinion Z on the power-shaft m with the pulleys n, the latter being driven by a belt n. Arranged on the same shaft is a pulley o, by which power is conveyed to a shaft p, pulleys p', belt p", and pulley 23" for operating the grinding-wheel u and polishing-wheel fu. By the train of gear-wheels thus described, which may be modified to suit any peculiar conditions, the high speed first applied by the belt n is reduced materially, so that the rolls c c are driven with great power, but at a comparativelylow rate of speed.

To provide for or admit the-inclinations of the rolls before described, I have coupled IOO said rolls e c to the shafts of the gear-wheels e e by coupling-spindles s. These are provided with square or angular recesses at their extremities adapted to receive correspondingly angular heads upon the shafts f, the joints admitting a freedom of action suiiicient to allow for the inclination of the axes of the rolls to the axes of the gear-wheels. This variation, however, in movement :may be allowed for without such lo'oseness of the joints by a limited bending or springing of the coupling spindles. I prefer to form through said coupling-spindles s and coperating parts water-passages connecting with the interior of the rolls C c, whereby the said rolls may be kept at a low temperature by means of a supply of water or other fluid, the said rolls being chambered out, as indicated in outline in Fig. l, to receive a body of such fiuid. Suitable Y supply and waste pipes are provided, as indicated.

To hold the rod or shaft to be rolled at'a proper point between the rolls, I have provided adjustable guides t. (Shown more clearly in Fig. 5.) These are arranged upon or within the bearings b b and are held in proper relation by means of adj listing-screws s' s. These said adj usting-screws enable the said guides to be held in proper parallel relation with one another between the rolls close to the periphery of the rod or wire and to beheld apart a distance equal to the diameter of the desired rod, so that the said rod will have a free movement longitudinally therebetween, but be prevented from springing laterally out of proper relation to said rolls, as will be understood.

After passing through the rolls and guides as described the rod passes into suitable supporting-bearings or pillow-blocks t t', by means of which it is held firmly as it moves forward. Between said bearin gs are arranged finishing-wheels, such as the grinding-wheel u and buffing-wheel t'. These latter are arranged upon a suitable shaft or shafts or journals and are driven by power in any manner convenient, but preferably by the pulley and belt 19 p". These said finishing-wheels are so disposed in their relations to the centers of the blocks or bearings tl t as that the peripheries of said wheels will engage the rod or shaft as it rotates in the said pillow-blocks 'L' t', and thus give to the said shaft a high polished and finished appearance equal or superior to the finish given to the ordinary shafting by the hand operations heretofore employed after turning.

I also provide at oppositeends of the machine at suitable points stands tu w, by means of which the rod or shaft is held prior to and subsequent to passing to and from the machine. The said stands prevent said shafts or rods from bending or dropping out of line.

Both the pillow-blocks t z5 and the finishing-wheels u and o are made adjustable to accommodate varying sizes of shafts or rods. The wheels u and o have their journalbear ings u upon a sliding plate a', arranged in suitable ways in the bed-plate a, said sliding plate being controlled by an adj Listing-screw a, Figs. l and 7.

The jaws of the pillow-blocks t t are movable to and from one another to vary the size of the rod-aperture formed between, as indicated more clearly in Figs. 2 and 6. In Fig. G, t" indicates the body of the pillow-block, provided with a slideway for one of the jaws t" thereof, providing a support for the rod. Said jaw i" is adjusted on the slideway therefor by a screw 15" and is itself provided with a slideway for the second jaw 25"1. Said second jaw is moved to and from the first bythe screw t", and thus by means of said screws said jaws are brought into proper relation to hold the rod against the polishing-wheels.

The rolls care arranged in sliding boxes within the bearings Z2 and are adjustable by means of screws b to admit of the variations in the sizes of the rods, as will be understood upon examination of Fig. 4. To continue to rotate the rod or shaft after the end thereof has passed from between the reducing-rolls, whereby the said end will properly engage the polishing-wheels while being propelled forward by a second rod or shaft, I employ a belt and pulley or drum 3 and et, Fig. l, which belt is bent over said rod, so as to turn the same as desired.

In operating the machine after setting the parts in motion the rod is simply arranged in the forward stands and fed back to the rolls c, after which the action of the rod becomes entirely automatic, being drawn by the reducing-rolls to the polishing-wheels and by them finished for the market.

Having thus described the invention, what I claim as new isl. The combination with a bed-plate and suitable driving mechanism, of a pair of reducing-rolls arranged on axes inclined to the line of movement of the rod to give to said rod or shaft a longitudinal movement in addition to its rotary movement, and grindingwheels arranged in close proximity to said reducing-rolls and receiving the rotating rod therefrom to polish the same, substantially as set forth.
